The other day I was thinking in the shower (not an uncommon occurrence) and an idea occurred to me. Is there a smallest discrete unit of time? Not of measurable time, but is the space between one second and another infinite like the number line? Or is there a smallest unit of time that exists?

File this one under “stuff I’ve never heard of until now” –
Planck’s time – it’s the shortest length of time, defined as the time it takes light to travel Planck’s length (636.32×10−36 inches).
